The implementation of a sustainable urban mobility circuit in medium-sized cities can improve mobility and reduce the carbon footprint on the environment. The key to achieving this is to invest in infrastructure and technology, and to foster cooperation between different actors, including the municipal government, private companies and society in general. It is important to carry out an awareness campaign to involve citizens and achieve effective implementation. By creating a sustainable circuit, the use of alternative means of transport, such as bicycles and efficient and sustainable public transport, is promoted. With adequate investment, medium-sized cities can achieve more sustainable mobility and improve the quality of life of their inhabitants.
